6. tlc just got serious.

simple but effective

 While checking out the cases threads 2 appear to be stripped . No big deal. Dig out the cases second chance - the helicoil kit. This kit puts a threaded insert into the original hole to replace the damaged thread with a new steel one of original size. Only three steps to it realy.
1. Drill with drill supplied in kit. preferably on pilar drill to keep it all square .
2. Tap with special tap supplied in kit.
3. Insert helicoil insert with tool in kit. The insert has a tang to drive it in with. Turn in until approx 1 to 1.5 turns under surface and snap off and remove tang.
Job done .All threads ready for assembly.

special tap does its work
